The IESG has approved the following document: - 'Multi-Path Time Synchronization' (draft-ietf-tictoc-multi-path-synchronization-07.txt) as Experimental RFC This document is the product of the Timing over IP Connection and Transfer of Clock Working Group. The IESG contact persons are Suresh Krishnan and Terry Manderson. A URL of this Internet Draft is: https://datatracker.ietf.org/doc/draft-ietf-tictoc-multi-path-synchronization/ Technical Summary Clock synchronization protocols are very widely used in IP-based networks. The Network Time Protocol (NTP) has been commonly deployed for many years, and the last few years have seen an increasingly rapid deployment of the Precision Time Protocol (PTP). As time- sensitive applications evolve, clock accuracy requirements are becoming increasingly stringent, requiring the time synchronization protocols to provide high accuracy. Slave Diversity is a recently introduced approach, where the master and slave clocks (also known as server and client) are connected through multiple network paths, and the slave combines the information received through all paths to obtain a higher clock accuracy compared to the conventional one-path approach. This document describes a multi-path approach to PTP and NTP over IP networks, allowing the protocols to run concurrently over multiple communication paths between the master and slave clocks. Working Group Summary The document has clear working group consensus for publication, and has been reviewed by several WG participants since its initial adoption as a working group item. Document Quality There have been multiple reviews of this document within the WG and it has been revised to address those reviews. Personnel Karen O'Donoghue is the document shepherd. Suresh Krishnan is the responsible Area Director.
